Serial No. 408,618.

To oll'whom it may concern:

Be it known that I, ALBERT S. JANIN, a citizen of the United. States, and a resident of the city of New York, Rosehank, borough of Richmond, in the county of Richmond and State of New York, rave invented a new and useful Improvement in Trolleys, of which the following is a full, clear, and exact de scription.

The purpose of the invention is to provide a trolley with a collapsible diamond-shaped frame, spring and pneumatically operated, so designed. that it will reliably operate at all times, especially when used in high speed work and in connection with heavy traffic; and it is also a purpose of the invention to so construct the trolley that it will he completely under the control of the motorman, and so that it will not leave the wire without being purposely withdrawn therefrom.

Another purpose of the invention is to provi lo a simple and d uraltle trolley, which while light in structu will withstand the se vere lateral strain consequent on the running of the car at high speed on a straight track, and on curves.

Another purpose of the invention is to so construct the trolley that in passing over railway crossings it will invariably reach the wire, and further, when. a train carrying the trolley is run in tunnels and subways, it will successfully work in very low head-room.

is likewise a purpose of the invention to provide a trolley that does not need reversing, since it operates as successfully in on e direction. in the other, and which when taking the current from the third rail may be collapsed. to lie close to the root of the car or locomotive, at the will of the person in charge.

it a further purpose of the invention to provide a trolley that will be noiseless in operation, and wherein the contact roller is designed to give it long life, the roller being accompanied by a scraper adapted to remove ice from the wire, and wherein also the roller can be locked. and made to act as a scraper or slide.

A further purpose of my invention is to have the trolley raised and held in operative position by pneumatic pressure and. provide means also to look it in said. position and work from that position when the air is exhausted.

Another purpose of my invention, which is very vital, is to have means when the trolley is not in operative position to relieve the springs of their tension and let them expand to their normal position, whereas in other trolleys when they are lowered and kept in position for a length of time the springs be come compressed and lose a great deal of their tension.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter set forth and pointed out in the claims.

Reference is to be had to the accompanying (,lrawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation. of the improved trolley expanded to its full position; Fig. 2 is a similar view 3ut illustrates the trolley fully collapsed; Fig. 3 is a plan view of the trolley; Fig. is an enlarged side elevation of the central portion of the trolley, parts being in section; Fig. 5 is an enlarged longitudinal section through a portion of the contact roller; Fig. 6 is a side elevation of one end of the contact roller, illustrating a modified. form of the bearing therefor; Fig. 7 is a sectional end view of the contact roller shown in Fig.6; and Fig. 8 is a section taken practically on the line 88 of Fig. 6.

The frame of the trolley consists of two upper bars A and A at each side, and two corresponding lower bars B and B. These bars are connected at their outer end portions by suitable connecting rods 10, the connection being so made that when the trolley is in place the entire frame can be dropped to the lower flat position shown in Fig. 2, or can be elevated to the position shown in Fig. 1. The inner ends of the lower members B and B of the frame are mounted to turn upon a tubular base C, which is in the nature of a cylinder and is adapted to be secured to the top of the car or locomotive or other vehicle to which the trolley is to be applied. The inner ends of the lower bars B and B are bifurcated, as is shown in Fig. 3, providing thereby an outer member ii and an inner member 11, the two members at each bifurcated portion of the lower bar being parallel, as is also shown in Fig. 3, and the outer edges of the said members 11 and 11 are rounded oil or are rendered segmental, as is illustrated at 12 in Fig. 8, but the inner ends of the outer members 11 at the bifurcated end of the said lower bars B and B are provided with teeth 13, and the said toothed portions are segmental, corresponding to the curvature of the opposing portions 12 above mentioned. -ransversely opposing segmental sections of the frame are connected by transverse bars 14, likewise shown in Fig. 3, and these connecting bars insure that the sides of the frame shall have uniform movement.

Each base C is provided with a tubular extensions, and these extensions are dcsig-- nated as 15 and 15 as illustrated in Fig. 4 the sections or extensions 15 and 15 are shown as being screwed to the base C to which they belong, but it will be understood that they can be otherwise attached, or that they may constitute an integral portion of said base. Each base C is provided at each side of the center at its upper surface, with a lug or bearing, the lugs or bearings being designated as 16, and. the members 11 and 11 of the lower bar sections B and B, of the frame, are pivoted to these lugs by means of suitable pivot pins 17, as is shown in Figs. 3 and 4. The inner ends of the upper bar sections A and A of the frame terminate in toothed segments 18 and 18 and these toothed segments 18 and 18 are pivotally connected with cheek pieces 20 by means of suitable pivot pins 19 and 19 The teeth of the segments 18 and 18" are adapted to mesh as likewise the teeth of the lower seg' ments 11, as is shown in Fig. 2.

A guard lip 21 is made to extend outward and downward from the cheek pieces 20, a sufficient distance to form a shield or a protective medium for the upper segments 18 and 18. In addition to the aforesaid guard lips 21, guide arms 22 are likewise made to extend downward and outward from the cheek pieces, the guide arms being integral with the aforesaid guard lips, as is shown in Fig. 5. These arms 22 are adapted as directors for the wire. A bearing 23 is located at the inner side of each cheek piece 20, as is illustrated in Fig. 5, and these hearings are circular and are hollow and are provided with openings in one of their sides, the openings being designated as 24, and these bearings 23 are pivoted to the said check pieces by means of suitable pivot pins 25, as is also shown in Fig. 5. Each bearing 23 is provided at its outer face with opposing openings 26 located preferably near the periphery of said bearings, and either one of the openings 26 is adapted to receive the inner end of a pin 27, that is preferably screwed into a cheek .piece 20, as is also shown in Fig. 5, soas to hold the bearings 23 in adjusted posi-' tion.

A scraper 28 is made to connect the bearings 23, the scraper being segmental in cross section, and the convexed face of the scraper 28 is flush with the outer or peripheral face of the bearing 23, and the scraper 28 is attached to the said bearings 23 by means of suitable bolts 29, or the equivalents thereof. A shaft 30 is made to extend from the central portion of one bearing 23 to the central portion of the opposing bearing, said shaft having transverse shoulders 30 near the ends to stop end movement, the bearings turning loosely on said shaft, and the said shaft 30 carries a contact roller D and the heads of the said contact roller are in two sections, an inner section 31 and an outer section 32, the inner section 31 of the heads being secured bykeys or otherwise to the shaft 30, and the outer sections 32 of the heads of the said roller are free to turn upon the fixed inner sections 31. on ball bearings Preferably the roller D is constructed as shown in Fig. 5, consisting of an outer metal tube 34 that is carried over the heads of the roller and is secured to the outer sections 32 of said heads, and an inner tube 35 of rubber, together with a spiral spring 36 that has bearing against the rubber tube 35 and serves to force the said rubber tube against the outer metallic tube.

Each cylindrical base (1 is provided at its central portion with an opening 37, and each of said openings 37 receives a pipe 38 that connects the bases together and leads to any source of compressed air, under the control of the motorman or other person attending to the direction of the vehicle. Opposing plungers 38 are located in each cylindrical base C, being one at each side of the opening 37, and these plungers are acted upon by the compressed. air that enters the said cylindrical base 0, and a spring 39 is located in each extension 15 and 15 of each cylinder or base 0, the inner ends of the said springs having bearing against the outer ends of the plungers 38*, and the outer ends of the springs 39 have bearing against cylindrical blocks 40, that slide in the said extensions 15 and 15 and a pin 41 is passed through each of these blocks 40, and said pins 41 extend out beyond the opposite sides of the extensions 15 and 15 from the base, through longitudinal slots 42 produced in said extensions, as is best shown in Fig. 4. A piston rod 45 is attached to each outer end of each ofsaid pins 41, and these piston rods at their inner ends are pivotally and eccentrically connected with the toothed sections 11 form ing a portion of the lower frame bars B and B, so that when air under compression is admitted. to the bases (7, the plungers or pistons 38 are forced outward, placing the springs 39 under compression, and likewise carrying the pins 41 in an outward direction, whereupon the piston rods 45 are likewise carried outward, thus causing the frame members to be separated and carried upward to the position shown in Fig. 1. When bers return to their lower position, the upper members lying flat upon the lower members, as is shown in Fig. 2, and both the upper and lower members at such time are substantially parallel with the top of the car or other vehicle, as is illustrated also in Fig. 4.

In order to assist the frame in risin and likewise to provide a cushion for the upper members of the frame when the said frame is in its lower or collapsed position, a. tubular pocket 43 is formed at the central portion of each base *9, being open at top and bottom, and the said pocltets extend out through the top portions of said bases, and in each of the said pockets 43 a plunger 44 is located, hav ing a lower and an upper head, the upper head being the larger one and is designated as 45. 'ihis upper head is held some distance above the top of the base ii carrying it, means of a suitable spring 45, and when air is forced into the base C it forces the plunger 44 upward and since when the frame is lowered the cheelr pieces rest upon the larger head 45 of said plungers, the plungers rise they assist the upper members of the frame in rising, and when the frame is collapsed the cheek pieces will come in engagement with the upper heads 45 of the said plungers, when the upper members of the frame have reached their lowest position, and thus the plungers under these circun'istances will. act as cushions for the upper portions of the frame, as is illustrated in Fig.

When the frame is in its lower position, the lower members thereof are supported by lugs 47 carried thereby adjacent their inner ends, which lugs rest upon the upper faces of the bases 0, said lugs keeping the frame in horizontal position. The contact roller D may be locked stationary so as to act as a scraper when desired, and this is accomplished by means of a pin 48, one of which is located in the inner wall of each bearing 23, and the said pins when employed are made to enter the outer or movable sections 32 of the heads of the said. roller. The object in making the bearings 23 rotatable and in providing means for locking the said hearings in adjusted po sition, is to carry the scraper 28 either to a point below or a point above the said contact roller.

in Fig. 6 l have illustrated a slight modification in the construction of the upper portion of the frame, wherein the bearings 23 are omitted and lik wise the scraper, and the cheek pieces 49 are provided with openings :30 extending through them, and while the guide arm 22 is omitted, the cheek pieces 49 are provided with guard lips 51 as in the other form of construction. The check pieces 49 at their inner ends are provided *ith diagonal slots 52 that receive the trunnions 53 of the contact roller D, as is shown in Fig. 8.

In Fig. 7 I have illustrated a slightly different way of connecting the upper or inner ends of the upper frame members A and A to the check pieces 49. The said attachment is accomplished by pivoting the upper ends of the said upper frame members to said cheek pieces by means of simple pins 54, the gears or teeth being omitted from this portion of the said bars and instead segmental slots 55 are produced in the said inner ends of the said upper frame members A and A, and bearings56 secured to the check pieces 49 are made to extend outward through said slots.

The inner ends of the upper frame members are inwardly curved where they connect with the cheek pieces, as is shown at a in Fig. 3. It will be observed that the bifurcated parts 11 and 11 of the lower frame members constitute toggles. id hen the contact roller is locked it acts as a sliding hearing, and it may be here remarked that the pistons or plungers 38 are provided with packing rings 58 fitted in grooves in their peripheries at their inner ends, to allow said packing rings to have full compression, the outer end portions of the said pistons or plungers being of lesser diameter, as is shown also in 4.

The plungers or pistons 38 are provided with annular exterior grooves 59, and a recess 60 is formed in the base wall of each recess, as is shown in Fig. 4, which recesses are adapted to receive pins 61, that extend through the base, when the pneumatics is not used. At such time, the springs 39 are employed to hold the trolley frame in its upperposition, being placed under tension and held so by forcing the plungers or pistons outward and causing the pins 61 to enter the recesses 60.

The piston rods 45 are made in two sections connected by a coupling 62, so that they can be adjusted to compensate for wear; and where the piston rods 45 receive the pins 41, slots 63 are made to admit of play of the plungers after the collapsing of the frame.
